Tips for ordering

Cantidad

Al encontrar la cantidad de concreto que necesita, las medidas no siempre son exactas, por lo que recomendamos enfáticamente a nuestros clientes que ordenen un poco más. Una buena regla general es tomar su cálculo y agregar cualquier parte del 5-10% del total para tener en cuenta los desechos, derrames, excavaciones excesivas, asentamientos, pérdida de aire incorporado y otros cambios en el volumen. Recuerde, puede ordenar concreto en incrementos de media yarda.

Depresión

El asentamiento es una medida de la consistencia del concreto. Un revenimiento de 4 pulgadas es ideal. Tenga en cuenta que agregar un galón de agua por yarda cúbica puede disminuir la resistencia a la compresión del concreto en 150-200 psi, desperdiciar cemento y aumentar la contracción en un 10%. Esto puede ser problemático para aquellos que vierten en condiciones de congelación/descongelación.

Fuerza

Strength is most commonly measured by the designed compressive strength in pounds per square inch (PSI) of a hardened cylinder of concrete. Any slab exposed to freeze thaw conditions should be a minimum of 4000psi. Estate concrete offers 3500, 4000, 4500, and 5000 psi concrete.

Concrete Washout

You will need to provide a contained area for trucks to washout. This area would not allow fluids to seep into surrounding areas. We have portable washout boxes available for a fee. inquire with dispatcher.

Air entrained concrete

Air-entraining admixtures facilitate the development of a system of microscopic air bubbles within concrete during mixing. They increase the freeze-thaw durability of concrete. We recommend you order air entrained concrete when pouring in freezing/thaw conditions, or for concrete exposed to weather.

Non-Air entrained concrete

Air entrained admixtures should not be used on floors when attempting to achieve a dense and smooth surface.

Non air entrained concrete is ideal for interior work, and for hard troweled finishes.

Admixtures

Sika 440

Sika 440 is a hydration controlling admixture this allows the concrete to stabilize for long periods without affecting the concretes durability.

Fibra

Fiber reduces crack growth and increase the impact strength. Fiber-reinforced concrete improves resistance against freezing and thawing.

Calcio

Air-entraining facilitate the development of air bubbles within concrete during mixing. It increase the freeze-thaw durability of concrete, increase resistance and improve workability.

Acelerador

Accelerator makes concrete set faster by increasing the rate of hydration also they promote strength development so it happens earlier in the set time of a slab.

Calcio

Calcium produces an accelerated rate of hydration in cement while also warming the concrete mixture and allows workability of placement in cold weather.
